- OpenStack is an open-source cloud computing platform that provides infrastructure as a service capabilities. It allows workloads to scale out across thousands of virtual machines. - The document discusses challenges faced by service providers in adopting OpenStack, evolving workload types, and key features of the OpenStack Juno release including improved support for bare metal provisioning, NUMA awareness, and networking functionality. - The OpenStack community summit in Atlanta saw growing attendance and increased involvement from large enterprise users in areas like network functions virtualization.

3. WORKLOADS ARE EVOLVING
TRADITIONAL
WORKLOADS
● Typically resides on a single large
physical or virtual Machine
● Cannot tolerate any downtime
● Needs expensive high availability tools
found in VMware vSphere
● Application scales up rather than out
OPENSTACK TORONTO 3 | STEPHEN GORDON
CLOUD
FUNCTIONS
● Workload resides on multiple Virtual
Machines
● Tolerates VM failure – if one fails, another
quickly replaces it
● Fault tolerance often built into workload
● Application scales out rather than up

4. WHY OPENSTACK
● Brings public cloud-like capabilities into your datacenter
● Provides massive on-demand (scale-out) capacity
● 1,000's → 10,000's → 100k's of VMs
● It's OPEN!
● Provides flexibility to customize and interoperate
● Open APIs for interacting with interchangeable
backends
● Community development = higher “feature velocity”
● Features and functions you need, faster to market over
proprietary software

5. OPENSTACK MISSION STATEMENT
“To produce the ubiquitous Open Source Cloud
Computing platform that will meet the needs of
public and private clouds regardless of size, by
being simple to implement and massively
scalable.”
OPENSTACK TORONTO 5 | STEPHEN GORDON

6. OPENSTACK CIRCA “ICEHOUSE”
CLOUD INFRASTRUCTURE FOR CLOUD WORKLOADS
● Modular architecture, designed to easily scale out
● Based on (growing) set of core services

7. TROVE
● OpenStack Database-as-a-Service (Trove)
● Provides scalable and reliable Cloud Database as a
Service provisioning functionality
● Supports relational and non-relational database engines
● Provision and manage multiple database instances as
needed
● API supports JSON and XML to provision and manage
instances

9. OPENSTACK SUMMIT
● Six monthly User and Developer conference.
● Nov 2013 – “Icehouse” summit in Hong Kong.
● May 2014 – “Juno” summit in Atlanta.
● Nov 2014 – “Kilo” summit in Paris.
● General track provides venue for traditional presentations
on user stories, new features, and vendor solutions.
● Developer track provides less structured slots for
discussing features and roadmap for coming release.

10. JUNO SUMMIT RE-CAP
● Held at Georgia World Congress Center in Atlanta in
May
● ~4,500 attendees (~3,500 in Hong Kong 6 months prior)
10 OPENSTACK TORONTO | STEPHEN GORDON

11. TECH PREVIEW: TROVE
● OpenStack Database-as-a-Service (Trove)
● Provides scalable and reliable Cloud Database as a
Service provisioning functionality
● Supports relational and non-relational database engines
● Provision and manage multiple database instances as
needed
● API supports JSON and XML to provision and manage
instances
*Tech Preview features are subject to change in GA

12. JUNO SUMMIT RE-CAP – SUPERUSERS
● Increased visibility of “superusers”
● Keynotes including content from:
● AT&T
● Sony
● Wells Fargo
● ...and others
● Operators track in the design summit
● Neutron vs nova-network
● Upgrades
● Launch of http://superuser.openstack.org/

14. JUNO SUMMIT RE-CAP – NFV
14 OPENSTACK TORONTO | STEPHEN GORDON

15. JUNO SUMMIT RE-CAP – NFV
● Aim to decouple network functions from physical
infrastructure while maintaining performance.
● Increased presence from Communication Service
Providers (CSPs), Network Equipment Providers
(NEPs) etc.
● Formation of NFV subgroup to gather and work on
requirements.
● Similar to “win the enterprise” working group
launched at the Juno summit as well.

17. JUNO RELEASE PROJECTS
● Integrated:
● Sahara – Formerly Savanna - Big Data service
● Incubated:
● Ironic – Baremetal Hypervisor Driver
● Zaqar – Formerly Marconi, multi-tenant cloud
messaging service like Amazon SQS
● Designate – DNS-as-a-Service

19. TECHNICAL COMMITEE FOCUS AREAS
● Neutron feature parity with nova-network
● Migration strategy for moving between the two
(live/cold)
● Scalability – multi-host versus distributed virtual
router
● Test coverage in Tempest
● Retrospectively was integrated too early, policy
changes since applied.
● Which leads to...
19 OPENSTACK TORONTO | STEPHEN GORDON

20. TECHNICAL COMMITEE FOCUS AREAS
● Heat and Ceilometer gap coverage
● Updated integration requirements being applied
retrospectively to integrated projects.
● Scaling issues with both projects in some scenarios.
● Not abstraction layers in the same fashion as some
of the other projects (e.g. Nova and Neutron).
● Documentation coverage improving.
